LEROY A. FISI-I, OF CLOQUET, MINNESOTA.

.AIRSHIP.

To all whom t 'may concern.'

Be it known that I, LEROY A. Flsu, a citizen of the United States, residing at Cloquet, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Airships, of which the following is a specification.

This invention appertains to the type of machines for navigating the air, embodying planes, whether usedA in conjunction with a buoyantl field or not.

The purpose of the invention is to devise a novel mechanism automatic in operation for maintaining the machine on an even keel, thereby avoiding the casualties attributable to the machine losing its balance.

In accordance with this invention a weight is utilized as the controlling means, since .it tends to gravitate and at all times maintain a definite relative position. The weight is connected to planes which are provided for holding the machine level and other means are supplied and act upon the governor planes in opposition to the weight, so as to level the machine and maintain the same in an approximate horizontal position under all conditions.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective view of a flying machine constructed in accordance with my invention; Fig. 2 is a side elevation of the same; Fig. 3 is a top plan view of the machine; Fig. 4 is an end view.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The machine illustrated is devoid of propellers or steering means, it being under stood that any kind of rudder or propelling means such as commonly employed in dirigible flying machines may be employed.

i The framework may be of any desired type and is here shown formed of upper and lower frames 1 and 2 connected by corner posts 3, vertical end braces 4 and spaced intermediate side braces 5 and 6. Extending longitudinally of the framework are upper and lower truss rods 7 and 8 having their opposite ends connected with the adjacent frames 1 and 2 at the vertical braces 1, and

their intermediate portions connected by spaced vertical rods 9 and 10. The rods 9 and 10 are disposed in alinement with the side b 'aces 5 and G and are connected with the latter by transverse rods 11 and 12. The rods 11 and 12, together with the side braces 5 and 6 and vertical rods 9 and 10, divide the framework into three independent sections or compartments, the intermediate section or compartment being adapted to receive the stationary lifting planes 13 and the end sections or compartments, the movable or governor planes 14. 'lhe lifting planes 13, any number of which may be employed, are rigidly secured to transverse rods 15 connecting the braces (S and are preferably inclined downwardly, as shown. These lifting planes also prefe ably increase in width from the bottom of the franiework to the top thereof to enable each plane to catch the wind and thus act as a parachute in fase of an accident.

The governor planes 14 serve to hold the machine level and also serve to direct the flight of the machine when ascending or descending, as will be more fully explained hereinafter.

The rear longitudinal edges of the governor planes of one set are rigidly secured to transverse rods 1G connecting the intermediate side braces 5, while the rear longitudinal edges of the governor planes of the other set are rigidly secured to transverse rods 17 connecting the adjacent corner posts. The forward longitudinal edges of both sets of governor planes are also rigidly secured to the adjacent end braces 4, the corners of the planes being free and normally supported in a horizontal position by coil springs 1S.

The lifting springs are preferably secured to the upper frame 1 at the corners thereof and are connected with the adjacent governor planes so as to normally exert an upward pull thereon.

The governor weight 19 is suspended below the framework of the machine and is mounted to move bothV longitudinally and laterally, said weight being in the form of a car in which the motor and adjunctive parts, and the operator are carried.

The governor weight or car 19, is suspended from the lower truss rod 8 by means of a depending frame, the latter comprising spaced parallel links 20 pivotally connected at 21 to vertical clips 21 rigidly secured to the upper and lower transverse bars 90 The lower transverse connecting bar 22 is held against rotation by suitable brackets Q8 on the car, while the upper transverse bar is suspended from suitable sleeves or collars 211 journaled on the lower truss rod 8, thus to allow both longitudinal and lateral swinging of the suspension frame and car.

Mounted for rotation on the car 19 is a winding drum or windlass 25 to which are connected a plurality of ropes or cables 2G, the latter being also connected to the corners of both sets of governor planes for the purpose of deflecting or warping the corners of said planes when the machine is tilted and thus cause the machine to right itself and maintain an even keel. The upper ends of the ropes or cables are connected in any suitable manner to all of the governor planes of the adjacent. set, so that all of the planes of each set will be warped or deflected downwardly when a longitudinal pull is exerted on the adjacent cables, and deflected upwardly simultaneously by the action of the springs 18 when the pull or tension on the cables is released.

The windass is provided with suitable pawl and ratchet mechanism 27 for preventing rearward rotation thereof and also with a handle or crank 28 by means of which the operator may wind the cables upon or unwind said cables from the windlass so as to either slack or place the cables under tension for the purpose of adjusting the position of the governor planes when ascending or descending.

From the foregoing it will be understood that when the machine isv level, whether in flight or at rest, the cords or cables 26 are under like tension and hold the corner portions of the governor planes level. Should the machine when in flight depart from an even keel either by dipping forward or rearward or incliningV laterally, either to the right or to the left, the weight or car 19 relatively moves and pulls the cords or cables 26 upon the high side of the machine and slackens upon the cords or cables upon the low side, thereby lowering the planes v'upon one side and permitting the springs 18 to elevate the planes upon the opposite side with the result that the machine is quickly arighted or brought to a level position. Vhen it is desired to ascend, it is merely necessary to rotate the crank 28 in one direction, which renders all of the cables slack and causes the springs 18 to elevate the corners of both the front and rear set of governor planes. In order to descend, the crank is rotated in the opposite direction which causes the cables 26 to deflect or,warp the corners of both sets of governor planes downwardly, the stepped arrangement of the stationary lifting planes 13 causing the machine to gradually settle to the ground.

The upper and lower frames 1 and 2 are preferably reinforced and strengthened by the provision of diagonally disposed brace rods 29, while the truss rods 7 and 8 are also preferably reinforced by similar brace rods or wires 30.

lt is to be understood that the weight may be of any construction and that the governor planes may be of any formation, arrangement or number so long as the parts, by reason of their arrangement, move the planes to bring` about the results herein stated. 1t is also to be understood that a separate weight may be employed for actuating the governor planes in lieu of the car and that said weight or car and governor planes may be used in connection with any type of flying machine without departing from the spirit of the invention.
